Tucking it into something works great, if you have something to tuck it into! If you're mounting on light poles or the middle of a structure, that doesn't work.
Also doesn't work for commercial installations. You'll be expected to do a professional install where the wires are in conduit. So you just have a box at the end of the conduit, mount the camera to the box cover, drill hole in cover for the wire, then seal with silicon.
